the odor could possibly be from a bacterial infection, i have had them and then smell it wretched!
Hi There,
Crystaly is absolutely correct. I hope you go to the nearest ER. If it is still in there, you can become very sick from toxic shock.
If you think you didn't remove your tampon please go to your Dr or nearest emergency room. You can get quite bad infections eg. toxic shock if you have left a tampon inserted. The fact that you cannot remember is enough to visit a docter. Its much better to be safe than sorry. If you have removed it then theres no harm done. If you have not removed it then it needs to be taken out.
